Data

A persistable set of key/value pairs which are used as inputs and outputs for ListenableWorkers. Keys are Strings, and values can be Strings, primitive types, or their array variants.

This is a lightweight container, and should not be considered your data store. As such, there is an enforced MAX_DATA_BYTES limit on the serialized (byte array) size of the payloads. This class will throw IllegalStateExceptions if you try to serialize or deserialize past this limit.
